What is known as "true skin" or "cutis"?

The term "true skin" refers to the dermis. This layer of skin is located beneath the epidermis and is responsible for many of the skin’s critical functions, including providing strength and elasticity through its dense network of collagen and elastin fibers. The dermis contains essential structures such as blood vessels, hair follicles, and sweat glands, which play key roles in thermoregulation, sensation, and overall skin health.

Understanding the composition of the skin layers is fundamental for procedures in electrolysis and laser treatments, as the dermis is the layer where significant processes occur, influencing healing and the effectiveness of various skin treatments. The other options, while they represent different layers of the skin, do not encompass the structure or functions associated with "true skin." For instance, the epidermis is primarily a protective barrier, while the hypodermis and subcutis refer to deeper layers that vary in structure and function compared to the dermis. Thus, recognizing the dermis as "true skin" highlights its vital role in skin integrity and health.
